Definitions

  • the present invention relates to a terminal device for subscriber telephone interconnection.
  • Such a device is normally in the form of a box which may be disposed out-of-doors, and therefore subjected to bad weather. Its purpose is to connect the telephone line to one or more subscribers.
  • a first compartment which is directly accessible when the cover of the box is opened, and which contains the connections for the installation of the subscriber, or subscribers if there is more than one subscriber telephone line connected by this box;
  • a second compartment which is accessible only if a second cover, generally closed by lead-seal, is opened and which contains the connections for the operator, i.e., the public or private Administration charged with telephonic distribution.
  • test socket generally of the "modular jack” type which is placed upstream of the two terminals for connection to the box of the line of the subscriber's installation, and electrically in series therewith.
  • This test socket is composed, on the one hand, of a female "modular jack" base which is directly connected on the incoming line, at the outlet of the compartment reserved for said Administration, and, on the other hand, of a complementary male socket or plug, also of the "modular jack” type, which is provided at the end of a portion of twin-wire cable, of which the other end is connected to the said two terminals for connection to the interface box of the two wires of the line of the subscriber's private installation. If this male plug is introduced in this female base, continuity of connection is ensured, and this private installation is supplied.
  • the invention relates to a terminal device for telephone interconnection of at least one subscriber, which is in the form of a box divided into two clearly distinct compartments, viz. a first compartment which contains the connections for the Administration or private enterprise charged with telephone distribution and which is generally not accessible to the subscriber, and a second compartment which is accessible to the subscriber and which therefore contains the connections for his private telephone line or lines which are connected to the corresponding line or lines of the Administration or Enterprise via this terminal interconnection device, this second compartment containing, for each line, a test socket composed of a telephone socket connected directly on the line of the Administration or Enterprise and at the output of said first compartment reserved therefor, this socket being adapted to receive, in order to test correct functioning of the Administration's or Enterprise's installation, the conjugate socket which normally equips a subscriber terminal or telephone set, the device being characterized in that:
  • the electrical interconnections are not made by wire connections, but by non-wire connecting means such as metal blades or cut-out metal circuits,
  • the telephone socket is associated with electro-mechanical means, which, when the conjugate socket of a terminal or telephone set is naturally connected in this socket, then bring about automatic cut-off of the electrical connection which existed between this socket and the corresponding private line of the subscriber.
  • FIG. 1 is an exploded partial view in perspective of a first embodiment of this terminal box for subscriber telephone interconnection.
  • FIG. 2 is an exploded view in perspective of one of the two specific subscriber modules which equip the interconnection terminal of FIG. 1.

  • FIG. 9 shows this box according to FIG. 8 in the same way, with the two covers removed and its plug-in module for protection against overvoltages as well as its R-C module not yet plugged in.
  • FIG. 10 is an exploded view in perspective of the terminal interconnection box according to FIGS. 8 and 9.
  • FIG. 11 is a view in detail of the interconnection terminal of FIGS. 8 to 10, showing how the insertion of a telephone socket in its contactor brings about disconnection of the line on the subscriber side.
  • FIG. 12 is a top view, similar to FIG. 7, of a third embodiment of this interconnection box, with solely its principal cover open.
  • FIG. 13 shows this box according to FIG. 12 in the same way, with this same principal cover closed.

  • FIG. 15 is a view similar to FIG. 12, showing this same box with its two covers, "principal” and “telephone distribution side”, both open.
  • FIG. 16 is an exploded view in perspective of a more universal variant embodiment of the terminal box of FIG. 10.
  • FIG. 17 shows the terminal box of FIG. 16, but ready to be equipped with a subscriber module with "modular jack” socket and not with a subscriber module with French contactor.
  • FIGS. 18 and 19 are a view in section and a plan view from underneath, respectively, of the support plate, showing very schematically how the connection of the plug-in contactor equipping the box of FIG. 16 is effected.
  • FIGS. 20 and 21 are views similar to FIGS. 18 and 19, but relative to the plug-in modular jack socket equipping the box according to FIG. 17.

  • FIG. 29 is a plan view of the interconnection terminal according to FIG. 27, with the incoming and outgoing wire connections made.
  • FIGS. 1 to 7 show a first embodiment of a telephone interconnection terminal device which, in this example, may ensure interconnection of two subscriber lines on two corresponding lines of the general telephone network.
  • An interconnection terminal of this type is very generally in the form of a box 1 of plastic material which is intended to be positioned on a wall, either inside or outside a building, dwelling house, offices or other premises.
  • the inner part of the box 1 is divided, which is not novel per se, into two distinct compartments, viz. (cf. for example FIGS. 3 and 7), a first compartment 4 which is directly accessible when the principal cover 3 is opened and which contains all the interconnection connections for the two subscribers, and a second compartment 5 which is accessible only when a secondary closure cover 6, employing screws and generally with lead-seal, is opened, and which contains all the connections for the Administration or Enterprise charged with telephone distribution and which will be referred to here as "Distributor", as opposed to the consumers, or "Subscribers".
  • the principal cover 3 and the secondary cover 6 are mounted to rotate on a common axis 8.
  • Other forms of embodiment of these covers exist, as will be seen hereinafter, all this being conventional per se, contrary to what follows.
  • this interconnection terminal comprises no internal wire connection, the only wires that it contains being (FIG. 7), on the one hand, the four end wires 10, 11 and 12, 13 of the respective two incoming lines 14 and 15 and, on the other hand, the four end wires 16, 17 and 18, 19 of the respective two outgoing lines 20 and 21 towards the two subscribers, as well, moreover, as the two respective earth wires 22 and 23, all these wires being introduced into the box through a rubber passage 24.
  • each of these modules is a module of the type now largely distributed and sold by the Applicant company under reference "MX" which is virtually identical to that described in U.S. Pat. No. 4,767,354 and in particular shown, under reference 1, in FIGS. 1, 3, 4 and 6 of this U.S. Patent. However, it is screwed in a base 27 of plastics material which serves as support for all the elements placed in the box 1, and which is rendered fast with the bottom 2.
  • the two contacts 28 are not necessarily tubular contacts, but flat contacts with upper self-stripping slit as well, preferably, as with lower self-stripping slit, which is then fitted on the edge of the corresponding longitudinal metal blade 29 or 30.
  • the two longitudinal metal blades 29 and 30 are parallel and each located in a vertical longitudinal plane. To some extent, they form a metal "bus" which ensures the electrical interconnection in parallel of all the elements of the box 1 which concern the same telephone line. In the present case, there are two telephone lines, and therefore two respective pairs of blades 29, 30 and 57, 58 and consequently two "busses".
  • the insulating wall 33 which defines the separation between the two compartments 4 and 5 is an integral part of the base 27.
  • R-C module On the interconnection bus 29, 30, there are also plugged, in the compartment 5 for the Distributor, a module 36 for protection against overvoltages and a module 35 intended for remote line tests, called "R-C module".
  • the protective module 36 which contains a three-pole overvoltage arrester 34, is a conventional plug-in protective module and more precisely a module such as described in French Patent Application No. 93 05049 and marketed by Applicants under reference "MXP".
  • the transverse blade 44 is fixed beneath the base 27 by a median metal screw 45 of which the end penetrates in a median metal contact 46 which receives the said earth wires 22 and 23.
  • the stripped ends of these two earth wires are clamped in the contact 46 by means of a screw 47 (cf. in particular FIG. 6).
  • the R-C module 35 is shown in detail in FIG. 5. It is directly fitted on the two blades 29 and 30 by means of two conjugate tuning fork contacts 48 and 49. It comprises, in its plastic envelope 50, a capacitor C and a resistor R which are connected in series as shown between the two line wires. This R-C module makes it possible to effect frequency tests of the line from the auto-switch of the distributor, and therefore at a distance.
  • the two pairs of blades 29, 30 or "interconnection bus” do not extend only along the compartment 5, but extend up to and into compartment 4 which concerns the connections for the two subscribers.
  • connection between each bus 58, 57-29, 30 and the stripped ends of the respective two corresponding line wires, 16 and 17 for a first line 20 towards a first subscriber, and 18, 19 for the second line 21 towards the other subscriber, is effected in each case by means of a very particular module 51, 52 (cf. FIGS. 1 to 7), which is fitted by clipping on one of the two ends 53, 54 of the base 27 which occupy compartment 4.
  • a very particular module 51, 52 (cf. FIGS. 1 to 7), which is fitted by clipping on one of the two ends 53, 54 of the base 27 which occupy compartment 4.
  • One of these two modules is shown in exploded view in FIG. 2.
  • the two tuning fork contacts 55, 56 constitute the lower ends of two more complex metal contacts 59 and 60 (FIGS. 2 and 3) which are captive of the plastic body 61 of the module 51.
  • these vertical contacts are each folded downwardly and towards compartment 5 to form two fine elastic plates 62 and 63 which constitute the two conventional line contacts of a female socket 64 of "modular jack" type which equips half the upper part of the module 51 which is the closest to compartment 5.
  • This socket 64 is therefore normally permanently connected to the two terminals 29, 30 or 57, 58 of the incoming line.
  • the subscriber may connect thereto his own telephone set in order to test the correct functioning of the circuits placed upstream, i.e. correct functioning of the Distributor's circuits placed upstream of his private installation.
  • This socket 64 is normally concealed by a sliding cover 65 which is returned into position of closure (FIG. 3) by a return spring 66.
  • this cover or flap 65 performs an essential role, as the fact of opening it by pulling it under the action of spring 66 automatically disconnects the subscriber's circuits.
  • the metal contacts 59, 60 each present a horizontal tab 67, 68 directed towards the subscriber.
  • the flap 65 When, as shown in FIG. 4, the flap 65 is opened by pushing it back against the force of the spring 66 in order to disengage the input of the modular jack socket 64, the free end of the tab 73 pushes the supple blade 69 downwardly, which brings about opening of the switch 71, thus insulating this modular jack socket from the remaining part of the subscriber's installation.
  • each of the blades 69 and 70 is folded vertically and upwardly to form vertical contacts 74 and 75.
  • Module 78 receives the subscriber wires 16 and 17 and module 79 receives the subscriber wires 18 and 19.
  • FIGS. 8 to 11 Another embodiment of this subscriber telephone interconnection terminal box will now be described with reference to FIGS. 8 to 11, to which reference will now be made.
  • the device shown is provided to connect one subscriber only, instead of two as in the preceding example, and a French contactor replaces the previous modular-jack socket.
  • the bottom 2 of the box 1, which is divided into the same two distinct compartments 4 and 5, is closed by two respective adjacent covers 80 and 81, cover 81 being, of course, lead-sealed as it covers the Distributor's compartment 5.
  • compartment 4 receives a French contactor 82, instead of the previous modular jack socket 64, and cover 83 of this contactor 82 forms part of cover 81 and is therefore lead-sealed likewise.
  • Compartment 5 contains, like the preceding box, a module 84 for rapid interconnection of telephone lines, as well as an earth terminal 46. There is further provided, as in compartment 4, on each line wire, two conventional test sockets 86-95 each adapted to receive a complementary banana plug.
  • a protective module 87 identical to module 36 mentioned above, may in addition be fitted in this compartment 5 on tuning fork receiver contacts 88.
  • a conventional R-C circuit 89 normally covered by the lead-sealed cap 83, is plugged, by its two small connecting tabs 90, in two corresponding self-stripping connection slits 91 (FIG. 11) which are integral with the two elastic line connection blades 92 of the contactor 82.
  • a conventional connection pusher 93 makes it possible to plug the two tabs 90 of the R-C circuit 89 in the slits 91, without twisting them.
  • Compartment 4 for the subscriber's connections, contains in this example two rapid interconnection modules 94 which make it possible easily to have, for example, two telephone sets connected in parallel on the same line.
  • the line of the subscriber may very well be connected only on one of these modules 94.
  • This compartment also contains two test sockets 95, identical to sockets 86.
  • This box has the same functions as the previous box. It effects, on the one hand, all the connections without internal wire connections, and, on the other hand, the introduction of a French telephone plug in the conjugate contactor 82 automatically insulates the subscriber's private installation with respect to the incoming telephone line, as hereinbefore.
  • connection links are here ensured by a conventional cut-out circuit 97 which is housed beneath plate 27.
  • this plate may be moulded on this cut-out circuit.
  • a support circuit 96 made of plastic material, is integrated in the bottom 2 of the box. It gives firm support to the cut-out circuit 97.
  • the two elastic blades 92 are each crimped on a respective flat line connection 98, which is connected to the "Distributor" side or “outer connection side".
  • the two flat line connections 99 on the “Subscriber” side or “inner service side” are respectively connected to the free ends 100, inside the socket 82, of the two small elastic plates 92 of this contactor 82 by a simple elastic bearing contact 101.
  • the introduction of a conjugate male socket in the contactor 82 causes the free end 100 to recoil, which cuts the contact thereof with the conjugate end 101 of the inner service or subscriber service line 99, in non-wire cut-out circuit.
  • contactor 82 may be replaced by a modular jack socket with closure flap functioning as hereinbefore (FIGS. 3 and 4).
  • This device essentially differs from the one of FIGS. 1 to 7 by the fact that the compartments 5 (distribution) and 4 (subscriber) are placed side by side and not one behind the other. Consequently, as shown in FIG. 14, the interconnection links inside the box are effected, like the device of FIG. 10, by a cut-out circuit 102 applied beneath the base 27 and supported by a plastic circuit 96.
  • FIGS. 16 and 17 the latter (which should be compared with FIG. 10 of which it takes up the majority of the elements, consequently designated by the same reference figures), presents a part 83 of the lead-sealed cover 81 which in fact covers only the R-C circuit 89, and a very localized part 113 of the module 103 of the socket 82 reserving solely for the Distributor the opportunity of extracting the latter.
  • the contactor 82 itself and its electro-mechanical circuit 100-101 for automatic electrical insulation of the subscriber's line in the event of plug-in of said conjugate telephone plug, is constituted like a module 103 which may be plugged into the plate 27 and which embraces the same functions as those of FIG. 11.
  • FIG. 17 schematically shows, to replace the plug-in module 103 with French contactor 82 by another plug-in module 104 which, this time, contains a modular jack socket 64 presenting the same functionalities, with its cut-off flap 65, as those described hereinbefore with reference to FIGS. 3 and 4.
  • FIGS. 19 and 21 show a part 105 of the cut-out circuit which is housed beneath the plate 27 equipping the boxes according to FIGS. 16 and 17, and more precisely that part of this cut-out circuit, which, depending on the case, lies beneath the modular jack socket 64 of the plug-in module 104 of FIG. 17 or beneath the contactor 82 of the plug-in module 103 of FIG. 16.
  • the elastic contact blades 92 of the contactor 82 each present a tuning fork contact 106, 107 which are both provided to fit respectively on track P1 and on track P2, which both materialize the incoming telephone line (outer connection side). Their other free ends 100 then bear on the ends 101 of the conjugate tracks P'1 and P'2 which materialize the outgoing line (subscriber side) and which are separated from the first, P1 and P2, by an air gap 108.
  • the introduction of a conjugate male plug in the contactor 82 opens the electrical contact 100-101 and therefore insulates the subscriber line P'1, P'2.
  • module 103 with contactor is replaced by module 104 with modular jack socket 64
  • this modular jack socket 64 is associated (FIG. 20) with the same cut-out elements 67, 69, 71 as that of FIG. 3.
  • socket 64 and on the two blades 69 two couples of tuning fork contacts 109, 110 and 111, 112 which respectively fit, as shown in FIG. 21, on the couple of tracks P1, P2 and P'1, P'2.
  • the flap 65 according to FIGS. 17 and 3 then opens the switch 71 when it is pushed back to disengage socket 64.
  • cut-out circuit 105 accepts equally well the plug-in module 103 with French contactor and the plug-in module 104 with modular jack socket.
  • the terminal is provided to receive either one or two lines (FIG. 15), or solely one line and not two (FIG. 17).
  • flap 65 for closure of the modular jack test socket on the Subscriber side lies in the fact that, when this flap has been opened to disengage this socket, which brings about, ipso facto, disconnection of the line on the Subscriber side, it is then necessary to maintain this flap open with the finger, which virtually mobilizes the manipulator's hand.
  • these flaps are equipped with a spring 66 for elastic return into position of closure, but not with a system for blocking in open position.
  • FIG. 22 is a plan view of this latter variant, the two covers closing the box being open, as in the case for the embodiment shown in FIG. 15 with which this FIG. 22 should be compared.
  • This interconnection terminal is in this case equipped, in compartment 5 on the Distributor side and in compartment 4 on the Subscriber side, with all the elements and modules relative to two distinct incoming lines, connected by cut-out circuits, as hereinbefore, to two respective outgoing lines towards two distinct subscriber lines. It will be seen hereinafter that this terminal may also be equipped, and this is its principal advantage, solely with the elements and modules relative to one incoming line only, connected to one corresponding outgoing line towards the subscriber.
  • a set horizontal embodiment is thus attained which comprises, to the right, all the connections relative to compartment 5 and, to the left, all the connections relative to compartment 4, these two connections being located on either side of a separating partition, real or virtual, and being designed as totally separate from one another, apart from the local interconnection cut-out circuits, of course.
  • FIGS. 22 to 29 disregards the prejudice whereby two distinct compartments, here compartments 5 and 4, must be dealt with distinctly. Therefore, instead of providing two compartments 5 and 4 which are separate from all points of view, it is provided to constitute them by means of at least two plug-in modules which each comprise a half-compartment 5A relative to an incoming line and a half-compartment 4A relative to an outgoing line, and which are adapted to fit in a receiving box bottom 2 of the box 1, which box bottom is at the start virtually empty of connections apart, possibly, from the earth connections, one against the other in order thus to be able, if necessary, to recreate the two complete compartments 5 and 4.
  • plug-in modules which each comprise a half-compartment 5A relative to an incoming line and a half-compartment 4A relative to an outgoing line, and which are adapted to fit in a receiving box bottom 2 of the box 1, which box bottom is at the start virtually empty of connections apart, possibly, from the earth connections, one against the other in order thus to be
  • Each of these half-compartments comprises the complete connections relative to an incoming line and an outgoing line associated therewith. If one is interested only in one incoming and outgoing line, it then suffices to fit in this virtually empty receiving box only one of these modules. The other half of the box then remains empty and therefore does not comprise unused elements, as before.
  • insulating box 2 which forms the bottom of the box of this terminal is, before it receives either one or two plug-in modules such as module 113 (FIG. 24) and/or the identical module 114 (FIGS. 22 and 23), virtually empty.
  • it contains, as connection element, only a metal band 115 in cut-out circuit, which constitutes the earth connection and which is connected on the one hand to a terminal 116 adapted to receive from the outside an earth wire and connect this wire by means of a metal locking screw 117 and, on the other hand, to the median parts 118 and 119 for earth connection of two three-pin female sockets for connection by fitting two protective modules such as modules 36, 87 of the preceding embodiments.
  • Such a three-pin socket may be seen, under reference 88, in FIG. 9 and the same socket is a little more visible in FIG. 10.
  • this virtually empty, insulating box bottom 2 is designed to receive, as desired, either one or two plug-in modules 113 and/or 114.
  • two centering studs 120, 121 are provided on each plug-in module to cooperate with two respective corresponding receiving cavities 122 and 123 in box 2.
  • Small supple plates 124 are further provided on each module to cooperate, by clipping, with corresponding convex parts 125 of the box bottom 2.
  • FIG. 27 shows the box bottom 2 after the module 113 has been plugged in and positioned
  • FIG. 23 shows this same box bottom 2 after module 114 has been plugged in and positioned.
  • module 113 Apart from the earth connections 116, 117, 115, 118, 119 mentioned above which form part of the box bottom 2, all the connections relative to one incoming and outgoing line only is contained in module 113 for a first line and in module 114 for a second line.

  • FIGS. 25 and 26 are shown enlarged in FIGS. 25 and 26 respectively with its sliding flap 65 for closure of its test socket 64, here of the modular jack type, on the Subscriber side, on the one hand closed (FIG. 25) and, on the other hand, open (FIG. 26).

  • Compartment 5A on the Distributor side comprises (to be compared with FIG. 15), a conventional module 25 for rapid connection of the two incoming wires coming from the Distributor, as well as, on the one hand, the socket for receiving a possible R-C module and, on the other hand, the other two female sockets which constitute, with the said female earth socket 119 which is already in place in the box bottom 2 (cf. FIG. 24), the female socket for receiving a possible protecting module 36.
  • module 113 all the interconnections are made, as in the majority of the preceding embodiments, by means of a cut-out circuit (not shown) which is incrusted beneath the plate 126 of the module 113.
  • the sliding flap 65 is provided with a semi-rigid tab 127 in overhang and whose free end is equipped with a clipping hook 128.
  • the flap 65 When, as shown in FIG. 26, the flap 65 is opened completely to disengage the modular jack socket 64, the semi-rigid tab 127 passes beneath a corresponding crosspiece 129 of the body of the module 113, with the result that, at the end of the opening stroke of this flap, hook 128 clips behind this crosspiece 129, thus maintaining the flap 65 in open position, against the force of its elastic return device 66.
  • FIG. 28 shows how, by closing solely the lower half-cover 6 (compare with FIG. 3), only compartment 4 on the Subscriber side remains accessible (the outer cover 3 is not shown in this FIG. 28).
  • FIG. 28 clearly shows the two passages 130 and 131 through which the wire connections, on the Distributor side and Subscriber side, respectively, will pass.
  • FIG. 29 is a plan view similar to FIG. 22, but with only module 113 in place in the box bottom 2 and the three wire connections. 22 (earth), 10 and 11 (line) on the Distributor side placed in position and connected and the two wire line connections 16 and 17 on the Subscriber side placed in position and connected (compare with FIG. 15).
  • Compartment 5 may, for example, receive functional plug-in modules other than the protecting module 36 and the R-C module 35.
